(Insider) – A challenge in which people pose with the help of a red filter that makes them appear as a silhouette has taken over TikTok. Now, however, the trend has soured as tutorials to remove the filter — and expose the individuals — have proliferated online, BuzzFeed News reported.

Set to a mashup of Paul Anka’s “Put Your Head On My Shoulder” with Doja Cat’s “Streets” that was uploaded by TikTok user @giuliadinicolantonio, the silhouette challenge involves walking around in loose clothing and then dancing or posing when the music transitions, appearing as a silhouette backlit by a red light.

The trend appears to use Snapchat’s “vin rouge” filter for the red light effect. As a silhouette, participants wear less clothing than in the first part of the video, occasionally wearing lingerie or posing nude. Some videos associated with the trend have amassed millions of likes.
